Macro Photography with the Raynox 150

I’ve had a chance to try the Raynox 150 recently on both my Pentax M200/4 and my Pentax M100/4 Dental Macro.

The Raynox 150 and 250 are the same optics as the Raynox DCR 1.5 and Raynox DCR 2.5 but come together in a kit with the 52mm mounting plate. These lenses are very well made and are achromatic to deliver nice sharp images without aberrations.

These test results aren’t scientific or even done in a controlled atmosphere. They are just images for you to look at and evaluate to see the quality these lenses can produce.

The Raynox 150 is approximately a 208mm focal length with a diopter strength of 4.8, the 250 is about 125mm and an 8 diopter. Most people choose the higher magnifications of the 250 or 2.5, however with larger magnifications than 1:1 the DOF becomes very thin and the working distance becomes very close. I chose the Raynox 150 mainly for my longer focal length lenses to maintain a greater working distance for more light control while shooting. I bought the kit as I will probably want the 250 for my mid range standard lenses and will post results with those soon.

UltraViolet Photography with Hoya U340

Been working in UltraViolet photography with the Hoya U340 and an S8612 filter stack testing to see how low my two “accidental” UV sensitive lenses might go.

The Steinheil is rated to 320nm and previous test I’d done with the Lensbaby Soft Focus Optic showed it performed well with the U360, so decided to see how the Soft Focus Optic did at 340nm.

Both were shot at f5.6 as I’m finding UV needs allot of light. Does allow for limited depth of field though. A modified Yongnuo 560IV flash was used to produce the lighting.

The Stienheil does produce a well defined focus and the Lensbaby lives up to its traits of very nice soft focus effects.

BIG Problem with Pentax m 100mm f4 Macro

Just picked up a Pentax m 100mm f4 Macro with dental scale and decided to give it a test run in the yard.
1st under natural light on Helicoid K for 1:1 (clover blossom).

Next I tried 1:2 with diffused flash (bee).

Then I tried to lay stealth in some bushes but could never seem to lock focus before subject skittered away.
Took a while to figure out the problem.

DO NOT let the cat join you on that Macro outing.
Really like this lens, seems to produce as well as my copy of the Tamron 90.

Picked up this lens to try with IR as the Tamron 90 macro suffers from hotspots. It performs stellar with the Tiffen 87.

UltraViolet Photography and Lensbaby

UltraViolet Photography and Lensbaby

Recently I have begun trying to work with UltraViolet light and my full spectrum K1. I’m enjoying it very much as the learning curve is proving to be a real challenge.

Most of my older lenses (and non of my newer digital) transmit the UV spectrum very well but I’ve been lucky enough to come across a few that are permitting me to do a some hand held shots. I’m finding simpler lenses with fewer elements and cemented groups seem to be working best so far. I’ve picked up a few 4/4 Zenitons and hope to show the results later in the spring during the wildflower season.

Here are a few using an older Lensbaby Soft Focus optic. It is 2 elements in 1 group.

The following are the exposure settings, filters and light source I used while photographing a White Geranium.

All were shot at f5.6 and on a 25mm tube.

Macro Photography Lens Stacking

As I’ve mentioned on my macros page, I’m not a macro photography purist.
I don’t focus on achieving a 1:1 life-size ratio when photographing a subject.
I do prefer using dedicated macro lenses (at least close focus) or macro techniques while doing close focus work as I find there is less distortion than with wide angle lenses.
I also enjoy trying anything that will spur my creativity.

This last winter, I was reading a website on extreme macro photography lens stacking and came across an article about using the Pentax M200/4 as a barrel lens for micro-photograpy work.
Extreme-Macro is a fantastic site for studying anything to do with close focus work. There is a wealth of information ranging from techniques to lenses, lighting or magnification calculations.
The page I stumbled upon mentioned the Pentax M200/4 as a wonderful lens to couple with a microscope objective for extreme work.

As I have an old M200 that doesn’t get used in this digital age, I decided to pull it out and see what I might be able to do with what I already had on hand or at least low cost investment.
A 52mm-52mm coupling ring, a 52mm-40.5mm step-down ring (which I did have to buy) and my old Rodagon 105/5.6 enlarging lens reverse mounted.
I must admit here that I am often lazy about using a tripod unless doing night shots and still prefer using an optical viewfinder over the rear lcd so achieving and maintaining focus with any depth of field would be a challenge.
I was surprised at how easy this combination was to hand hold and still achieve nice photos with a magnification of approx. 1.9:1.
Also, it was a fantastic pleasure to view something larger than life and try to see it in an artistic style.

Next I tried a reverse mount combination of the M200 with a Sigma 24/2.8 for a magnification ratio of approx. 8.3:1.
The added weight of the Sigma made it much harder to handhold but still produced nice results, though even at f16 the depth of field is very shallow.
This will take a lot more practice to get the my creative sight going.

I have been enjoying this new artistic view of the world so much that I just purchased an old EL-Nikkor 50/2.8 enlarging lens to use in the field (don’t want to take my Rodenstock out into the elements)
and am now on the hunt for an infinity focus objective plus adapter.

Lensbaby Plastic Optic Revisited

Very busy this month but I was able to revisit the Lensbaby Plastic Optic and play with a bit of Macro Photography in the yard.

Very pleased with he results and really like the soft focus effect the lensbaby plastic optic offers.

And a few with IR:

IR Lens Hotspot Database

kolarivision.com has an excellent ir lens hotspot database already compiled; however, I noticed most of my older film lenses weren’t included so decided to create a database (bottom of page) testing these lenses on the Pentax K-01.

Pentax A50 f2.8 macro & K-1

Recently pulled out the old Pentax A50 f2.8 macro for a few shots of autumn leaves in the back yard.

This lens performs wonderfully on the new Pentax K-1. Though not a “true macro” with a reproduction of 1:2, I find the scale adequate and the IQ superb; plus it is such a joy to use.

I can see why vintage Pentax glass was noted for it’s quality, the colors are brilliant and the IQ is sharp for the area of focus. Bokeh is pleasantly pleasing also. This doesn’t seem to change on the new digital sensors either.

In fact, I find their performance is equal to or better than the newer digitally enhanced lenses.

 

National Automobile Museum – Reno

Every time I visit, I feel one of the most overlooked attractions, in Reno Nevada is the National Automobile Museum.

This place is amazing. It contains vintage automobiles in pristine and restored condition from the Harrah’s collection.

Era’s start with the early horseless carriages and vehicles built for commercial and race uses to the mid 1960’s. The history behind many of these vehicle is fascinating in itself but the architecture and art in their designs is beautiful.

Highly recommend this place for a visit. Entrance is in and out for the day and seldom more than a half dozen visitors at a time. Allows plenty of time to read, view and photograph this impressive collection.

Not much to write about this month, Just enjoying the Pentax K-1

Spending time this month reading about lenses and the Pentax K-1.

I find Pentax Forums a very nice resource for all sorts of material, lenses, cameras, flash, techniques – and not necessarily related to solely Pentax.
Easy to research articles and always someone willing to give a helpful reply.
Shots taken this month with the Pentax K-1 and various lenses or optics.

Pentax K1 testing Old Glass

Received the new Pentax K1 and decided to run a few test with the older vintage lenses I still have.

Nothing special with the images and minimal post processing, just to show the clarity. Have been pleasantly surprised with the results. I’ll list the lens below each shot posted for reference.

Kiron 28-105 2.8 (respectively), some vignetting at 28 and a little purple fringing. Still very sharp for its age. Shot at f8.

Tokina 70-210 4.5-5.6 (respectively), Slight purple fringing at 210, sharper than my current Sigma 70-200 2.8 APO DG. Shot at f8

Tamron SP90 Macro 1:1, very sharp. Shot at f8

yale lockset macro

Tokina 70-210 4.5-5.6 @210 with +10 Diopter, shot at f8. Some purple fringing with no hood but pleasantly surprised.

Why I appreciate a wide angle macro lens for regular close up photography.

Over the years I’ve found I enjoy close up photography more than any other type.

While not being true macro of 1:1 or 1:2 life size, I really like the feel and intimate perspective of being close to my subject.
With the advent of APS sized sensors in the Pentax line (which I shoot and am a proud Pentaxian), I find the crop factor to bring more of a telephoto angle of view than I really like.
I have eliminated most of my film era telephotos and focused on gaining lenses that will bring the wide angle perspective back to my view finder.
